# MaxCartierIndex -- an option to specify the maximum number to consider when computing the Cartier index of a divisor

## Description

Some functions need to search for the smallest positive integer $N$ such that $N$ times a divisor (usually the canonical divisor) is Cartier. The option MaxCartierIndex is used to specify the largest integer to be considered in this search.

## Functions with optional argument named MaxCartierIndex :

• "isFRegular(...,MaxCartierIndex=>...)" -- see isFRegular -- whether a ring or pair is strongly F-regular
• "testIdeal(...,MaxCartierIndex=>...)" -- see testIdeal -- compute a test ideal in a Q-Gorenstein ring

## For the programmer

The object MaxCartierIndex is .
